  • Patent number: 7819822
    Abstract: Body fluid sampling device comprising a skin-piercing element having a collection zone for receiving body fluid, and the device further comprising a fluid receiving means remote spaced apart from the collection zone so that body fluid in the collection zone will not contact the fluid receiving means initially. The collection zone takes up a very small volume of body fluid of about 10 to 500 nl in a very short time period of less than 0.5 seconds. The fluid receiving means may have a test zone for performing an analytical reaction. Fluid sample from the collection zone is automatically or manually transported to the fluid receiving means to contact the fluid with the test zone.

  • Patent number: 7815579
    Abstract: An integrated lancing test strip includes a test strip and a lancet packet coupled to the test strip. The lancet packet includes a sterility sheet enclosing a lancet to maintain the sterility of the lancet and prevent cross-contamination between the test strip and the lancet. The sterility sheet allows the lancet to be sterilized separately from the test strip. The sterility sheet gives the integrated strip a low profile, which is attractive for packaging multiple integrated strips in cassettes, drums, magazines or the like. In one form, the integrated strip is loaded in a meter that includes an adjustment mechanism that adjusts the position of the test strip relative to the skin being sampled. This allows the user to adjust the position of the test strip so as to not apply excessive pressure against skin, which could hamper bleeding from the incision in the skin.

  • Publication number: 20100145228
    Abstract: A device is constructed so as to define a capillary channel that draws a body fluid form a proximal portion of the capillary channel toward a distal portion. A counterbore defining a “ledge” not substantially normal to the center line of channel causes the meniscus of body fluid to be “biased” into a non-radially-symmetric shape. In one example, the bias draws the body fluid toward a testing element that is set into a groove in the main body of the device. In another example, hydrophilic and/or hydrophobic regions are created on or in device to produce the biasing effect. In certain configurations, device requires less blood to be drawn into the capillary channel for a successful test than if the biasing effect were not created.

  • Publication number: 20100069793
    Abstract: A bodily fluid sampling device comprising a lancet which can be advanced against a skin-piercing site to produce a droplet of bodily fluid. A transport medium is positioned sufficiently close to the lancing medium to retain a droplet of bodily fluid therebetween by capillary action. One of the two mediums has hydrophobic material on its surface and the other hydrophilic. Various mechanisms are provided for relatively displacing the lancing and transport medium to move the droplet of bodily fluid away from the skin-piercing end. Furthermore, multiple lancet assemblies may be provided in a barrel or disk configuration and indexed to the displacing mechanisms for sampling a skin site.

  • Publication number: 20100069943
    Abstract: A self-powered lancing drive system and lancing technique uses permanent magnets to initially store the potential energy that is converted to kinetic energy for extending a lancet during lancing. This self-powered lancing drive system is a pure permanent magnet drive that is highly reliable under numerous operating conditions. Permanent magnets can produce stronger magnetic fields at smaller sizes as compared to electromagnets. In one form, the lancing system has a drive permanent magnet that is kept fixed or stationary while the lancet magnet travels along the firing path. With the drive magnet being stationary, the lancet experiences fewer fluctuations in the magnetic field. The lancet vibrates less and is driven straighter into the tissue. In another form, a retraction magnet is positioned at the end of the firing path of the lancet, near the tissue, to enhance retraction of the lancet.
